CONCLUSION: The macular retinal thickness values measured with Stratus OCT were significantly higher than those measured with OCT1. Artefacts were only observed in cases of diabetic macular oedema and were significantly more frequent with OCT1 than Stratus OCT (10.5% versus 4.4, p<0.0001). With Stratus OCT, RT values were significantly higher, by 8.1% (7.8%), than with OCT1. The mean difference between the OCT1 and Stratus OCT measurements was 25 (SD 26.2) microm (p<0.0001). RESULTS: Of the 590 automatic measurements, 505 had no artefact, either with OCT1 or Stratus OCT. The paired mean RT values for each area and the type and proportion of artefacts were compared. In each eye, mean retinal thickness (RT) was measured automatically in the nine macular Early Treatment Diabetic Retinopathy Study areas and at the foveal centre, using OCT1 and Stratus OCT. 59 eyes were examined: 17 had a normal macula and 42 had a diabetic macular oedema.
